2 Claims.

This invention relatesto the class of lubrica- .tion, and pertains particularly to an improved lubricating fluid designed primarily for lubricating valves and other sliding parts of musical wind 5 instruments.

' The present invention has nondrying lubricating fluid which used upon valves and other sliding for its primary object to provide an improved free flowing and. may be freely parts of musical wind instruments, such as cornets, trombones or the like, without danger of damagin the metal of the'instrument and without becoming eventually gummy so as ing of the parts.

to require the cleanprovision of a soap in water solution having added thereto an oil or oils function of preventing the which forms the double drying out and gumming of the soap and providing additional lubricant for the parts to which the fluid is applied. More specifically the invention comprises a mixture or emulsion of water, kerosene, a soap the trade and oil of citronella. In making the water is first heated, Ivory soap chips,

After a complete solution kerosene oil is added and thoroughly mixed in so as to form an emulsion.

This emulsion is then permitted to cool and it then has added oil of citronella which will thin out the previously formed thickened liquid.

As a specific example preferred that the ingredients be taken in following proportions: 4

Water ..gallons.. Kerosene do 011 of citronella ounces Soap chips or powder (Ivory soap o! the invention, it is the wNH

The present inventionbroadly contemplates the While the soap preferred for use in this prepa. ration is that sold under the trade name pre viously referred to, other pure soaps may be exnployed, therefore it is-to be understood that the invention is not to soap chips.

It is well known that soaps have a certain degree of lubricating actiombut in the present case the use of a soap-and water solution alone, while efiective for a short period of time, would finally defeat the purpose for which it is used by drying out and hindering the movement of the instrument parts between which it -might be placed. For this reason the addition of kerosene and citronella oils serves the double function of w preventing the drying out of the soap after the water has evaporated and of adding an additional lubricant to the mixture. The combination of the kerosene with the soap and water mixture also tends to retard the evaporation of the water m of the mixture.

,What' is claimed, is: v

1. A lubricating fluid for the purpose described, comprising an emulsion consisting of a mixture of a fully formed soap, water in which the soap 25 is dissolved, kerosene oil, and citronella oil and which is. characterized by the factthat it remains thin and free-flowing under all conditions and does not gum.

2. A lubricating fluid for the purpose described, w consisting of an emulsion containing water one gallon, soap (chip, flake or powder) one-iourth ounce. the soap being dissolved in the water, kerosene oil two gallons, and oil of citroneila three ounces.
